<typeinfo> must be included before typeid is used

[hypermagik]

The following piece of code shows this error, even though typeinfo is included:

#include <typeinfo>

int main() {
    const std::type_info &ti = typeid(main);
    return 0;
}

file: 'file:///.../test.cpp'
severity: 'Error'
message: '<typeinfo> must be included before typeid is used'
at: '4,32'
source: ''

Operating System and version: Ubuntu 16.04.3 LTS.

VS Code version and if you are using the Insiders build: 1.16.1 (not Insiders build).

Relevant settings from your settings.json, c_cpp_properties.json, and/or launch.json files:

Thanks for reporting it. It repros on Linux, but not Windows.

This is also broken on macOS Sierra

[EECSGEEK]

This is also broken on Win-Platform

@EECSGEEK The error shouldn't occur on Windows unless the typeinfo header (or a header it includes) fails to be located (or fails to get parsed). Are there other errors in your problems window?

@sean-mcmanus

Program one(g++include cunistd.h)
(g++ compile is ok)

Program 2
But vscode [error]typeinfo must be included before typeid is used

My setting

[sean-mcmanus]

@EECSGEEK Oh, yeah, you're using mingw with clang-x64 mode -- that makes sense why it would behave like on Linux. The issue doesn't repro with the typeinfo header defined in the Windows SDK.

I've verified the fix is in our pending update branch for February.

[sean-mcmanus]

Fixed with the preview .vsix at https://github.com/Microsoft/vscode-cpptools/releases/tag/v0.15.0-insiders (our final release is planned for next week).

@hypermagik @Ortix92 @EECSGEEK The bogus <typeinfo> must be included before typeid is used error has been fixed with 0.15.0. We're still aware of additional bogus errors that we have issues tracking that we plan to have fixes in the next couple months or so. If you notice a new issue, providing a repro will help us get a fix sooner. Thanks.
